BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the
information provided herein is prior art or relevant to the presently claimed
invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Conventionally, Gas Insulated Switchgear (GIS) includes separate
compartments such as Breaker compartment and Disconnector Switch Compartment. The Breaker deals with on-load make break of an electrical circuit and can have three positions ON, OFFF and earth. The Electrical links or parts used in breaker or Disconnector switch are coupled with a robust mechanical system. This Mechanical system is responsible for switching the position of electrical parts which in turn change the configuration of Switchgear (i.e. Breaker Open DS On, Breaker Close DS Earth etc.). All this mechanical operations need to achieved at appropriate speed, so as to minimize the effect of arcing or welding of Electrical contacts.
[0004] Since these mechanical operations are taking place at high speed,
there should be proper assembly of the fixed parts and moving parts. If the assemblies are not properly aligned, the moving part and fixed part would collide on one another and it would be difficult to ensure proper DS contact overlap. Due to some assembly errors or loosely bolted jointed etc, this assembly can be misaligned after few operations. Hence, monitoring of the overlap is very important. Earlier, only visual inspection was done to monitor alignment. For this visual inspection, the gas filled in the tank needs to evacuated and hence only off load testing can be done. Keeping all the above points into consideration, a monitoring system is being developed to check and ensure proper overlap of Fixed and moving contact of Disconnector Switch.

[0005] There is, therefore, a need of a system and method for monitoring
the disconnector switch remotely or online.

[0033] As illustrated, a system 100 for monitoring of a disconnector
switch 102 can include an imaging device 108 configured at a pre-defined location in the switchgear, and the imaging device is configured to capture images of the one or more fixed contacts. The disconnector switch 102 can include a moving contact 104 that can be in a first colour. The disconnector switch 102 can include a one or more fixed contacts (106-1, 106-2, collectively referred as 106, hereinafter) that can be in a second colour. The moving contact 104 can be configured to overlap the one or more fixed contacts 106 while operating the disconnector switch 102, in a switchgear. The imaging device 108 can be configured to capture images of the one or more fixed contacts 106 before and after operating the disconnector switch 102. The imaging device 108 can be placed at a pre-defined position in the switchgear. The pre-defined location can be selected such that the imaging device 108 can capture images of the one or more fixed contacts.
[0034] In an embodiment, the captured imaged of the one or more fixed
contacts 106 can be in the second colour when the disconnector switch 102 is not operated, and the captured images of the one or more fixed contacts 106 can be in the second colour when the disconnector switch 102 is operated since the moving contact overlap the one or more fixed contacts at that time. The system 100 can include a processing unit 116 that can include one or more processors 112. The

one or more processors 112 can be operatively configured with the imaging device 108. The processing unit can include a sensing device 110 that can be operatively configured with the imaging device 108.

receive, from the imaging device 108, captured images of the one or more fixed
contacts 106 in form of frames. Based on the captured images, the system 102 can
identify a colour of the captured image by combining the frames of the captured
image. The sensing device 110 can be configured to convert the identified colour,
from the captured images, of the one or more fixed contacts 106 into a
corresponding frequency value. Further, the system 100 can compare the
corresponding frequency value, with a pre-stored frequency values to identify a
successful operation of the disconnector switch 102. The pre-stored frequency
values can correspond to one or more frequency values corresponds to any of the
first colour and the second colour. The comparison result can facilitate
identification the moving contact 104 corresponding to the one or more fixed
contacts 106 and hence operating mode of the switchgear (not shown).

and the one or more fixed contacts 104 can also be calculated. The sensing device 110 can comprise a colour to frequency converter. The operation of the disconnector switch 102 can be referred to change in operation modes from ON, OFF, and earth. The system 100 can be operatively configured with one or more mobile computing devices that can be further configured with one or more users the one or more users can be configured to detect the operating mode of the switchgear through the one or more mobile computing devices. The one or more users can also control functioning of the disconnector switch 102 through the one or more mobile computing devices. The system 100 can be operatively configured with the one or more mobile computing devices through any of a network and cloud.
